There was a whole price fixing thing for retro games that happened in the same time frame, so it’s not an experiment that could be run with only a single variable. Old hardware is going to become more expensive as time goes on, as it becomes harder to source; young people are finding a curiosity with old tech that has no mandatory online connectivity, for a host of reasons; and quite honestly, the Switch 1 launched with Mario Odyssey and Breath of the Wild in its first year, with Smash soon after, Mario Kart 8 being one of the best-selling games of all time even before the pandemic, and Animal Crossing would have done gangbusters regardless. I’m convinced the pandemic had little to do with its success, even if Animal Crossing has a major chapter in it.
